Barrel tuners for F-class Open?

[ridgeway]

My ftr barrel is machined down to 0.900" then a sleeve has been.put on it to always the fitting of my tuner . There for when the barrel burns out heat sleeve knock of barrel clean up locking agent and put on next barrel and use the same tuner .

Why not simply thread the new barrel and thread on the used tuner? Less risk of it breaking free from being glued on or shrunk fit?

Does anyone have a reference to a paper or article or discusses the physics what tuners are doing? I'm looking for more details than a simple explanation that it tunes to a barrel's accuracy node. thx.

So far, this the best reference that I have found.. http://www.varmintal.com/apres.htm

That's how our Smith does our ftr barrels. Havnt had the sleeve move or tuner come loose yet. Seems to work the way he does it no problems that I've seen. Plus the tuner we use requires a sleeve to be fitted to my barrels as I dnt run a standed manufactured tuner.
